No. 7,871,330 on Jan. 18, 2011, which is a continuation of U.S. Ser. No 10/971,349, filed on Oct. 22, 2004, and issued as U.S. Pat. No. 7,247,097 on Jul. 24, 2007, which is a divisional of U.S. Ser. No. 09/665,669, filed on Sep. 20, 2000, and issued as U.S. Pat. No. 6,902,482 on Jun. 7, 2005, which is a continuation of U.S. Ser. No. 08/977,806, filed on Nov. 25, 1997 and issued as U.S. Pat. No. 6,162,123 on Dec. 19, 2000. The entireties of these applications are incorporated herein by reference.
The present invention relates to interactive electronic games. More specifically, the present invention provides an apparatus in which a participant may input velocity and position information into an electronic game and receive physical feedback through the apparatus from the electronic game.
The electronic game industry has seen a dramatic evolution from the first electronic ping-pong game (“pong”) to the state of modern games and consumer home electronics. In general, hardware advances that have increased processing power and reduced cost have fueled this evolution. The increased availability of low cost processing power, as well as consumer expectation for improved game content, demands that new games be developed to take advantage of this processing power. This can be seen especially in the new 64-bit processing devices such as the Nintendo 64™ and the processing power available in home personal computer games and/or in arcade game platforms. These new hardware platforms are so powerful that a whole new genre of games has to be developed in order to fully utilize the hardware.
Electronic game input, traditionally, has been limited to joy sticks, button paddles, multi-button inputs, trackballs and even a gyro mouse that has a gyroscope means for determining the orientation of the mouse. Recently, Nintendo has deployed a “rumble” device to provide vibratory feedback to game console users. Traditional computer input means are well know to those in the arts and require no further discussion. The gyro-mouse, in the context of the present invention, however, deserves some further discussion.
The gyro-mouse, provided in U.S. Pat. No. 5,138,154 to Hotelling, the relevant portion herein incorporated by reference in their entirety, provides a means for using the gyroscopic effect in a computer input device to recover user input. The gyro-mouse provides a gyroscope contained within a ball so that ball may be rotated. This rotation translates into two-dimensional or three-dimensional motion for software receiving the gyro-mouse input to display on a computer screen. Thus, the gyro-mouse is somewhat an extension of the track ball paradigm for a computer input device.
The gyroscopic effect has also been harnessed for practical commercial applications. One of the more interesting gyroscopic effects is brought about through the principal of conservation of angular momentum. As witnessed in gyroscopic phenomena, a gyroscope creates a force at right angles to a force that attempts to “topple” the gyroscope. Thus, a gyroscope when left alone or mounted in a double gimbal arrangement allowing the gyroscope to move freely in both axes, will resist movement and/or attempt to hold its own angular position. Gyroscopes are also known to have precession due to the earth's effect on the gyroscope. Gyroscope precession is not especially pertinent to the present invention; however, its principles and mathematical proofs and formula are herein incorporated by reference.
The navigational arts also provide a means for harnessing gyroscopic phenomena to determine the inertial position of a vehicle such as an aircraft. In an inertial navigation system, the gyroscope is mounted in a double gimballed arrangement and allowed to rotate without resistance in all directions. As the aircraft turns, rotates, and/or changes direction the gyroscopic effect keeps the inertial navigation gyroscope at the same angle. High precision means are used to determine how much the gyrostat has rotated, in actuality the aircraft rotating around the gyroscope, and this measurement in combination with high precision accelerometers provides a means for tracking the change in an aircraft direction. This instrumentality in conjunction with precision timing and velocity measurements provides a means for continuously determining an aircraft navigational position.
In another application of the gyroscopic effect, a large gyroscope can be used to create an effect that in some aspects is the reverse that of an inertial navigation system. Here, a large gyrostat mass (the flywheel) can be use to stabilize or position certain objects such as spacecraft. In the spacecraft application, such as in U.S. Pat. No. 5,437,420, the relevant portions herein incorporated by reference in their entirety, large flywheels and high torque motors and brakes are used to topple the flywheel. The spacecraft then feels a moment of thrust at right angles to the torque that is applied to the gyrostat. This way, and in others such as the “pure” inertia of rotation of causing a flywheel mass to accelerate or decelerate rotation, spacecraft attitude may be changed through gyrostatic means. In other stabilization applications, gyrostats are used to stabilize platforms such as cameras and other precision instruments, in general by attaching a gyrostat to the instrument platform.
Gyrostats have been used in conjunction with wheels to provide linear propulsion. Through a systems of gears and linkages, U.S. Pat. No. 5,090,260, incorporated herein by reference in its entirety, provides a means for translating the gyrostatic toppling effect into a linear force for propulsion.
The present invention is an electronic games with interactive input and output through a new, novel and non-obvious player interface apparatus. The new player interface apparatus may be a hand held apparatus that may use sensors to determine the position of the apparatus and the gyrostatic effect to provide tactile feedback to the user. More particularly, in one embodiment of the present invention, the apparatus may be used in conjunction with software to create an electronic interactive sword game. In the sword type embodiment of the present invention, the hand held apparatus is preferably about the size of a three and/or four D-size cell battery flashlight and is adapted to be held by either one and/or two hands. The sword type device may be ornamentally decorated to resemble the hilt and/or handle part of a traditional and/or futuristic sword. Contained within the sword housing is a gyrostatic propulsion device from which the gyrostatic toppling effect is utilized to create a torque and/or the feel of sword blows on the sword handle and, thus, on the player holding the sword apparatus.
In overview, one or more gyrostat(s) inside the sword apparatus may be used as the “propulsion” gyrostat, hereinafter, the “propulsion gyrostat.” The propulsion gyrostat may be configured with a relatively “large” mass flywheel and a high speed electric motor to spin the flywheel and, thus, provide a source of gyrostatic power. The flywheel of the propulsion gyrostat may be configured in a double gimbal housing wherein each axis of freedom, for example, the pitch and yaw of the flywheel, may be controlled by high torque electric motors. By applying the appropriate voltage to the high torque motors, the propulsion gyrostat may be “toppled” in such a way as to create a calibrated torque on the whole sword apparatus, e.g., the sword housing. This calibrated torque may be used to simulate, inter alia, a sword blow as felt at a sword's handle. Through the interaction of successive sword blows, e.g., torque provided by the propulsion gyrostat to provide the “feel” of sword blows, and interactions with virtual swordsman opponents, the present invention provides a novel and exciting interactive sword game that physically involves the player interactivity with the game.
In the preferred embodiment, the present invention works in conjunction with an electronic game and/or under the control of the electronic game. Thus, game “play” and/or plot features can be used to enhance the effectiveness of the present invention in creating the illusion of sword fighting. For example, game “play” and/or plot elements may be used to encourage the player to conserve the rotational energy stored in the propulsion gyrostat. This conservation of energy may be rewarded in the game interaction by producing more “powerful” sword strikes when the propulsion gyrostat of the sword apparatus is at full power storage, e.g., optimal rotational speed and/or a large flywheel in the sword apparatus. Keeping the propulsion gyrostat at full and/or near full power storage allows the sword apparatus to create the maximum impulse torque available thereby creating the most effective and powerful sword illusion.
It is understood that the sword apparatus of the present invention may not need a blade but the blade may be represented in the virtual space in the game itself. This may be done either on the computer screen or through the use of virtual reality glasses and/or other display apparatus. Thus, in the virtual reality domain, the computer may generate a sword blade that appears to extend from the hand held sword apparatus of the present invention. However, a plastic blade and/or other ornamental blade extending from the apparatus are within the scope of the present invention.
In another embodiment of the present invention, other virtual representations of the virtual instrument that is representative of the object held by the player are within the scope of the present invention such as a gun, bazooka, knife, hammer, axe and the like and the gyrostat propulsion instrumentality of the present invention may be controlled accordingly to provide the appropriate feedback to simulate the virtual instrument. For example, in the gun and/or pistol embodiment of the present invention the gyrostat feedback means may be used to simulate events such as the “kick” from a gun, or the “crush” of a hammer blow.
Another feature of the present invention is to have a macro gyroscopically powered inertia navigational means on-board the hand held device. Such a small apparatus is available from Sony Corporation. The gyroscopic inertial positioning system may keep the computer game apprised of the spatial attitude and/or location of the sword apparatus in such a way that the game may provide the proper moments of torque on the motors to provide feedback to the player.
Yet another feature of the present invention is to use sensors, e.g., a receiver and/or a transmitter, on the sword apparatus and an array of sensors, e.g., receivers and/or transmitters, external and/or internal to the sword apparatus to determine the spatial attitude and/or location of the sword apparatus. In the preferred embodiment of the present invention, the sword apparatus uses infrared blasters, e.g., high output infrared transmitters such as those found on modern universal remote television controls, to output a pulse and/or timed emission of infrared light which may then be received at the remote sensors, which in the preferred embodiment are infrared receivers, whereupon the timing and/or phase differential of the received signals may be used to triangulate and determine the spatial position of the sword apparatus. An infrared output at both the top and the bottom of the sword apparatus may be used to determine the attitude of the sword apparatus and is within the scope of the present invention.
Game play and/or game plot may be used to encourage the player to maintain the sword apparatus within a predetermined field of play. For example, if the gaming program determines that the sword apparatus is positioned near the edge of a predetermined game field, the game software of the present invention may produce a virtual attack and/or event on the player from the center and/or opposite side of the game field to encourage the player to move the sword apparatus toward the “center” of the predetermined game field. It is understood that the game of the present invention may also use a “mysterious” force feature, discussed further below, to encourage the player to move the sword apparatus toward the center of the predetermined game field.
Economical high torque motors are found in many common children's toys such as radio controlled cars and other devices. It is understood, that the present invention may have a gyrostat of sufficiently high mass and may be “spun” at a sufficiently high speed in order to convey to the player, through the gyrostatic toppling effect, the desired tactile game effect and/or torque on the player. The torque on the propulsion gyrostat may be a calibrated and/or variable force and, therefore, the effect may be a calibrated and/or variable force imparted to the player. It is understood that the fictitious “light saber” sword as popularized in the Star Wars™ fictionalized universe may be an appropriate metaphor for the game of the present invention. In the light saber metaphor, because a light saber is a fictional device, the game effects and/or game plot may be optimized to work in conjunction with the sword apparatus of the present invention. For example, the blow of crossing swords may use a calibrated and/or variable tactile feedback to the player where low energy storage in the propulsion gyrostat may be coordinated with game interaction such as allowing an opponent's sword to partially and/or completely pass through the players “light saber” defense. In another example, the light saber metaphor may allow the light saber virtual blade to strike through objects and, thus, may require a relatively small tactile feedback amount, thus, creating the illusion of a powerful virtual sword that can strike through objects. In contrast to a virtual medieval sword, wherein the steel blade cannot strike through all objects and, therefore, the striking of an object, such as a virtual tree, may require a massive tactile feedback response in order to “stop” the sword blow cold. Thus, the illusion of the medieval sword may be lost because of overloading, e.g., over draining of the rotational gyrostatic energy, the propulsion gyrostatic tactile feedback means of the present invention. That is not to say, of course, that a medieval sword embodiment is not within the scope of the present invention, for indeed it is as well as swords and blades of all types and sizes.
The light saber metaphor may be most appropriate, here, because the light saber metaphor may allow a player to strike through walls, e.g., the light saber may cut through the virtual walls. However, the player may still feel feedback as the sword passes through a virtual reality object, e.g. walls. Allowing the object to pass through the virtual reality object without stopping it “cold,” thus, allows the system to conserve its rotational energy for other interactions with the game.
Another interesting aspect of the present invention is the ability of the software to lead a player's movements, as well as provide impact feedback. A good example of this would be, again, the Star Wars™ metaphor where the player is told to “feel the force.” The game of the present invention may apply a “mysterious force,” discussed further below, which is essentially a small torque from the propulsion gyrostat whereby the sword device may “lead” the player's sword blows and/or movement.
Another aspect of the present invention is the ability to network multiple game play stations to allow virtual sword fights between multiple players and/or the coordinated efforts of multiple participants. In a two player mode, conventional modern means may be used to connect game stations in a back-to-back configuration. Telemetry between the game stations may be used to convey positional, attitudinal and inertial mass, explained further below, of the respective sword devices between game stations. In another configuration, multiple players may-network together with a server computer acting as the communication hub between multiple game stations. A low cost network such as the internet may be used as the network transport protocol. Alternatively, one game station may be configured as a master station, acting as a communication master and other game stations may be networked to the master station.

Block 499 may represent the circuit board for the control circuits of the present invention. Control circuits 499 may have a suitable communication means such as a USART and/or ethernet and/or universal serial bus interface to receive data signals from the game controller 240. It is within the scope of the present invention to use external circuits and use analog controls signals and/or wireless analog and/or digital control signal to provide an interface between the sword apparatus and the game controller 240. In the preferred embodiment of the present invention, circuits 499 may contain a suitable protocol communications device or procedure to establish communications between the sword device and game controller 240. Circuits 499 may also contain the processing elements necessary for control and/or execution of software and/or software elements to effect control of the sword apparatus of the present invention. The control functions and/or part or parts of the control function may be moved into the game controller 240.
Block 400 may represent the control circuits necessary for the analog drive voltages for the propulsion gyrostat means 500. It is understood that because of the high torque available from is the propulsion gyrostat 500 separate control circuits such as high powered transistors and/or FETs may require separate circuits 400 to generate sufficiently large drive currents and/or voltages. The control circuits 400 and the digital control circuits, and/or microprocessor circuit 499 may be placed into a single integrated circuit group of circuits and/or on the same circuit board.
Block diagram element 600 may represent a gyrostat positioning system to determine the attitude of the sword apparatus of the present invention. One such miniature device is commercially available from Sony Electronics and or functionally as the device employed in U.S. Pat. No. 4,959,725, the relevant herein incorporated by reference. Positional device element 600 may be used to determine the position of the sword and the attitude of the sword in the X, Y and Z axes. Switch 201 and switch arm 202 may be a safety switch, in the “deadman” circuit configuration, held in place by the player's grip on the apparatus. Because of the high torque available in this game it may be desirable to have a kill switch connected to the sword apparatus 200 requiring that the user keep the switch depressed in order for power to be imparted to the torque propulsion unit. The game may be equipped with suitable straps, such as VelcroŽ straps and/or gloves, to maintain the sword within a player's hands and not allow the sword to flip out of a sword player's hands, much like a hand guard served in part, on traditional swords. The circular devices depicted at 300, 302 and 304 may be either infrared receivers or infrared blasters or transmitters. These sensors and more, not shown, may extend around housing 200 to detect the position of a sword and/or the spatial coordinates of X, Y and Z as is denoted and further discussed in

The main flywheel 10 is shown mounted in a double gimballed configuration. The first gimbal is along an axis between motors 30 and 35. The second gimballed axis is between motors 40 and 50. This is a (two axes of freedom) double gimballed apparatus meaning that both “pitch” and “yaw” of the main propulsion flywheel 10 may be controlled in two axes of freedom. Other mechanical configurations of double gimballed gyroscopic apparatus are known to those skilled in the art and are within the scope of the present invention. It is also understood that a single gimballed embodiment is within the scope of the invention that may utilize two and/or more gyrostats. Two propulsion gyrostats in a single gimballed configuration may be utilized by coordinating the toppling force on the two gyrostats to create the necessary torque action on the player desired by the present invention. It is also within the scope of the present invention to utilize two double gimballed gyrostats, one at the top of the sword and one at the bottom of the sword (not shown) in a “bar bell” like configuration. Such a dual gyrostatic propulsion configuration may be used to impart additional torque on the sword housing 200 to provide a more realistic simulation of the sword battle.
Sensors 37 and 38 are positional sensors that may be infrared and/or light-based sensors which may reflect off disks 100 and 90, respectively. Disk 90 and disk 100 may be reflectively “bar coded” to indicate the position of the flywheel within the gimbals via the coding of the reflected light from sensors 37 and 38 off of the disks. These positional sensors may be necessary to obtain the position of the flywheel 10, e.g., the pitch and yaw position, in order to calculate which way the propulsion gyrostat should be toppled to create the desired torque. Contacts 110 and 95 are shown as a means for transferring power and signals from the outer gimbal to the inner gimbal. Such power transfer may be accomplished by utilizing conductive metal ring fixated to disk 100 and disk 90 and pressure contacts at 110 and 95 keeping in contact with the conductive metal rings.
The main propulsion gyrostat is shown at 10. Spokes 15 hold the propulsion gyrostat to the axis 60 of the main drive motor 20. It is understood that an additional drive motor 22 may also be used. Housing 70 shows the housing of the first gimbal securing motor 20 and 22 and flywheel 10 to the first gimbal housing 70. The first housing 70 extends around to the mounting axles 31 and 32, connected to toppling motors 35 and 30 respectively. Drive motors 35 and 30 may impart the toppling torque in the first gimballed axis. It is understood that motors 30 and 35 may be replaced with a single motor and that configuration is within the scope of the present invention. Configurations that give the toppling motors 30 and 35 a mechanical advantage, such as with a mechanical gear arrangement, are also within the scope of the present invention. Circular ring 80 depicts the second gimbal housing holding motors 30 and 35 to a second gimbal arrangement. The second gimbal housing 80 connects the inner gimbal and motor drives 30 and 35 to the outer gimbal 80 through axles 81 and 82. Axles 81 and 82 are connected to the second gimbal drive motors 40 and 50. Once again, a two motor configuration is shown as a means for imparting the maximum torque available from small electric motors such as those available from the hobby and toy arts. It is understood that these toppling motors may work in tandem to impart a toppling torque in the same direction; likewise motors 35 and 30 may also work in tandem to impart the maximum toppling effect on the drive gyrostat, the drive flywheel 10. It is understood that motors 50 and 40 may be replaced by a single suitably high torque motor. It is also within the scope of the present invention to use configurations that give motors 40 and 50 a mechanical advantage for toppling the drive flywheel 10 via the inner gimbal. Inner and outer gimbal brakes and/or clutches (not shown) may be used to temporarily lock a gimbal axis which a toppling force is applied to the second gimbal axis, such as disclosed in U.S. Pat. No. 5,437,420, the relevant portions herein again incorporated by reference. Function circuit board 400 is shown as providing the analog drive voltages for the motors described above.
Procedural block 584 checks whether the controller 401 has issued a shut down command, if yes, the gyrostat position control loop exits at 586, if no, the procedure is passed to sword position routine 564 and the control loop goes on continuously (that is, until a shut down command is received). The check shutdown routine 584 may check the dead-man switch shown as
